Brightness & Gamma

Determines whether the game overrides monitor gamma (0) or uses desktop (1). Set to 0 for in-game gamma/overbright control—essential for custom brightness.

Enables direct GPU driver gamma access (NVIDIA/AMD). Keep on for reliable adjustments; off may limit control on some hardware.

Overall screen luminance multiplier. Higher values brighten dark areas without color shift. IPS/OLED often need 1.1-1.3; fullscreen required.

Ambient map geometry brightness multiplier. Higher makes shadows drastically lighter; 2-3 balances visibility without washout.

Multiplies the brightness of moving entities (players, items, weapons). If you use Vertex Lighting (r_vertexLight 1), you MUST set this to 2 or higher, otherwise enemy models will appear completely pitch black. Fullscreen required.

Acts as a saturation and vibrance multiplier. While Gamma washes the screen out with white light, Intensity specifically makes map and enemy colors 'pop' more aggressively. 1.1-1.2 enhances enemy visibility subtly.

Sets a hard limit on how bright map textures can become when using high Overbright settings. 255 allows full range without clipping—default for natural lighting.

Renders all textures on the map without any shadows or lighting. Warning: This is considered a cheat by the Quake Live engine and will NOT work in online multiplayer servers. Requires sv_cheats 1.
